The LoPy4 can act as a LoRa nano gateway and a multi-bearer (LoRa, Sigfox, WiFi and BLE) development platform suitable for all LoRa and Sigfox networks around the globe. It is programmable with MicroPython and the Pymakr plugins for fast IoT application development, easy programming in-field and extra resilience with network failover. You can also configure the LoPy4 in raw LoRa mode to send packets directly between LoPy4’s. The best blend of speed to deployment and access to new LPWAN networks rolling out across Europe, USA, Africa and India. The LoPy4 is CE, FCC approved, LoRaWAN and Sigfox certified.

Note: Using the LoRa or Sigfox radio without the external antenna can lead to damage of the device and is therefore not recommended.
